Yerbury’s Elf (Tetrathemis yerburyii)

A very rare endemic dragonfly of small size inhabits ponds and stagnant pools along streams of mid-hill rainforests. Museum specimens were so far collected from Hanguranketha, Hatton and Kandy (The dragonflies of Sri Lanka – Terrence the Fonseka). Therefore de Fonseka has noted that it is confined to the submontane areas of the island. However above picture was taken at the Horagolla national park (7° 8'29.44"N,  80° 5'2.83"E) a lowland rain forest patch of about 33acres in Gampaha district 170 ft a.s.l.
